Abstract: A process for manufacturing ball joints or other self-lubricated joints, comprising placing the inner ring of the ball joint in a heat-retractable sheath of determined thickness and shrinking the sheath on this inner ring. The inner ring is then disposed in an outer ring blank which is then deformed so that the sheath is clamped between the outer and the inner ring. After machining of the blank, the assembly is treated so as to eliminate the heat-retractable sheath and thus form between the two rings a free space whose thickness corresponds to that of the sheath. A self-lubricating resin is then injected in this space.
